Additional Details

This 2 inch Lead Free Reduced Pressure Zone (RPZ) backflow preventer assembly is engineered to protect potable water supplies from backsiphonage and backpressure, meeting national plumbing codes and water authority requirements. It is ideal for health hazard cross-connections, service line entrances, irrigation systems, and boiler feed lines. The assembly features a compact, modular design for easy maintenance and includes a flood sensor with SentryPlus Alert technology to detect excessive water discharges from the relief valve.

Key Features

  • Lead Free cast copper silicon alloy body construction for durability and compliance.
  • SentryPlus Alert flood sensor detects continuous discharge from the relief valve.
  • NPT inlet and outlet connections with pre-installed Viega ProPress adaptors.
  • Quarter-turn full port resilient seated ball valve shutoffs for reliable operation.
  • Single access cover and modular check construction facilitate ease of maintenance.
  • Top entry to all internals for immediate accessibility.
  • Captured springs for safe maintenance during servicing.
  • Internal relief valve design reduces installation clearances.
  • Replaceable seats for economical repair.
  • Includes two in-line independent check valves and four resilient seated test cocks.

An add-on connection kit is required to activate the flood sensor. Without the connection kit, the sensor is a passive component with no communication. Watts is not responsible for the failure of alerts due to connectivity issues, power outages, or improper installation.
